We look at the division of 4978630 by 591 
We're looking to find how many times 591 goes into 4978630.

On to step 1:
591 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 591

Moving on to step 2:
If we divide 49 by 591, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 591

Let's proceed to step 3:
591 can be fit into 497 0 times, resulting in a remainder of 497.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 497 and we're left with 497.
Include the next digit (8) from the dividend after 497, then repeat: 4978 / 591

Going ahead to step 4:
4978 divided by 591 is 8 with a remainder of 250.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 4728 from 4978 to get 250.
Include the next digit (6) from the dividend after 250, then repeat: 2506 / 591

Moving on to step 5:
If we divide 2506 by 591, we get 4 and a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 2364 from 2506 to get 142.
Fetch the next digit (3) from the dividend, attach it to 142 and continue: 1423 / 591

On to step 6:
If we divide 1423 by 591, we get 2 and a remainder of 241.
Record the quotient 2 as the next digit in the result. 
Result so far: 842.0
Subtract 1182 from 1423 to get 241.
Grab the next digit (0) from the dividend, add it to 241, then carry on: 2410 / 591

Step 7:
When dividing 2410 by 591, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 8424.0
Subtracting 2364 from 2410 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
591 goes into 460 0 times with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 8424.0
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 9:
591 can be fit into 4600 7 times, resulting in a remainder of 463.
Put 7 as the next digit of the answer. 
Result so far: 8424.07
Subtract 4137 from 4600 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 10:
The number 591 fits into 4630 7 times, leaving a remainder of 493.
Put 7 as the next digit of the answer. 
Result so far: 8424.077
Subtract 4137 from 4630 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

The final result is 8424.077 with a remainder of 0.0493.
